There's no Amazon channel specifically for manly/violent/escapist/crime/spying-related films and TV shows, as far as I know. But the fact remains that there is a wealth of great stuff on there, whether from Amazon itself, movies and TV shows licensed from other broadcasters, or from an impressive smorgasbord of 3rd-party, bolt-on 'channels', covering everything from art movies to old-time studio classics to horror. It would be ridiculous to describe anything the trillion-dollar behemoth Amazon does as some kind of plucky underdog success story, but Prime Video hasn't really received the props it deserves over the years.
As a result, the service is a little underrated. A lot of Amazon Prime Video users probably only use it because it comes bundled with Amazon Prime – the subscription deal that gives you free, next-day delivery of products.
